: Thanks Les!: So what you say is that I should put these controllers (A to D) assigned to cutoff, release, or whatever, for each of my programs and then tweak them. Then, while in the mix mode, I can assign the mix to work with the program that I defined before for these controllers, and that's it?: It seems to be somehow limited, though. When I imagine that a CS1X/2X/6X for instance has all this knobs for realtime control, at least I would expect the QS to be able to be diretly controlled by Cakewalk for such a purpose, without having to program it much. : How about that kinf of "Patchboy", or "Freakcontrol" hardware pads that come with silders and knobs for realtime variations... I mean, if I plug one of these thingies to my QS, will they control independetly all my midi channels on a mix, or no? : Any ideas?

I have a Roland JD-800, it has 59 sliders and many knobs and buttons, so it's made for real-time tweaking. Most sample playback machines (like the QS) are not that easy to control in real time. You have up to four voices per patch, and up to 16 patches per mix, so you would need a really complicated piece of hardware to tweak all that.

I also have an MM-16 MIDI mixer, it has 16 assignable faders, and it can do various controllers even sysex. It's a pretty useful controller, you can check out the specs at the link below :
